Operation)
Elevation Error:
!
<00> During calibration, the
potentiometer feedback did not
change while the elevation
motor was running.
!
<01> During calibration, the
limit switch was detected as set
before and after the motor
started, and the potentiometer
feedback changed.
!
<02> During calibration, the
potentiometer reached
maximum or minimum and the
limit switch was not reached.
!
<03> During calibration, the
potentiometer feedback for the
maximum and minimum limits
were too close together.
!
<04> During calibration, a
timeout occurred waiting for the
limit switch to be reached.
!
<05> During normal operation,
the potentiometer feedback did
not change while the motor was
running.
Checks the elevation racks and elevation system.
1. Powercycle the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This may be an isolated
incident.)
2. Inspect the elevation racks for any obstruction/foreign objects
lodged between the gear teeth.
3. Check the elevation racks for any apparent damage to the gear
teeth, or bending of the racks.
4. Check the elevation drive shaft (between the elevation racks)
for damage or bending.
5. Check for loose wiring and connections between the elevation
motor and the e-box.
6. Check the power board and processor board test points verify
they are operating within the test range. See “Power Supply
Voltage Checks and Fuses” on page 6-27.
7. Check for damage to the elevator capacitor.
8. Replace the elevation potentiometer with a known working POT.
(If the problem persists...)
9. Replace the elevation motor with a known working motor. (If the
problem persists...)
10. Replace the processor board. See “PCBs and Power Supply
Replacement” on page 7-28.

Over Temperature Error (*C)
<XX>
(where XX equals the
temperature in Celsius)
The ambient temperature inside the e-box has reached 65° C
(149° F).
1. Remove power from the GE T2100 Treadmill and allow to cool
off.
2. Power up the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This may be an isolated
incident.)
3. Check the power board and processor board test points and
verify they are operating within the test range. See “Power
Supply Voltage Checks and Fuses” on page 6-27.
4. Verify appropriate operating environment, 10°C to 40°C (50°F
to 104°F)
5. Replace the processor board. See “PCBs and Power Supply
Replacement” on page 7-28.
